Synthesis of biomaterials; nanomaterials; biodegradable polymers; dendrimers; drug delivery; imaging contrast agents; self-assembly

Dr. Gillies’ research involves the design, synthesis and application of functional molecules. The molecules of interest can range from well-defined oligomers and dendrimers to higher molecular weight polymers. In particular, the group is interested in the interactions of these molecules and their supramolecular assemblies with biological systems to serve as new biomaterials and therapeutics. For example, polymer assemblies may be used as nanocontainers to control the localization within the body of therapeutics ranging from small molecules to proteins and DNA. They may also serve as new scaffolds to display biological ligands, thereby providing new therapeutics or materials for tissue engineering. We are also investigating polymers that degrade by novel mechanisms in response to biological stimuli in order to achieve an unprecendented level of control over the polymer degradation process. Research is also underway to develop new contrast agents for medical imaging.

Rheology and microrheology of polymers, nanocomposites, gels, and other soft materials.

Dr. de Bruyn's research aims to establish the links between the microscopic structure and bulk properties of complex fluids. He uses shear rheometry, dynamic light scattering, microscopy, and other techniques to study the microstructure and viscoelastic properties of complex fluids on both the microscopic and bulk scales. He also studies flow and flow instabilities in complex fluids and granular materials using a variety of flow visualization methods.

Scanning Probe Microscopies, spectroelectrochemistry and other instrumental analyses: toward optoelectronic, biological, pharmaceutical and environmental applications.

Dr. Ding’s research group is applying modern analytical methods such as electrochemistry, spectroscopy and microscopy to multidisciplinary research. His team specializes in the development and applications of scanning electrochemical microscopy (SECM), Raman microspectroscopy (RMS), atomic force microscopy (AFM), near-field scanning optic microscopy (NSOM), electrochemiluminescence (ECL), and their combination. He is applying these techniques to cell imaging, electroluminescence and the development solar cells.

Planetary Materials 

Dr. Roberta Flemming is an Associate Dr. in the Department of Earth Sciences, and Director of the Powder X-ray diffraction (pXRD) and micro X-ray diffraction (μXRD) Facility (since 2001). She specializes in Earth and planetary mineralogy, studying mineral structure and cation ordering, and as functions of pressure, temperature and composition. She also measures/calibrates strain and strain-related mosaicity in minerals which have undergone tectonic deformation or have been shocked by meteorite impact. She studies minerals from the Earth’s mantle and a variety of meteorites (e.g., chondrites, achondrites, martians), as well as synthetic analogues. Minerals of interest include spinel-group minerals, olivine, clinopyroxene, kimberlite indicator minerals (e.g., garnet), and diamond. She collaborates to study natural glasses, clay minerals and natural zeolites.

Bioengineering & Regenerative Medicine, Biomaterials & Scaffolds, Molecular & Cell Biology, Skin Disorders & Wound Healing

Dr. Flynn’s research interests focus on the development of cell-based regenerative approaches with adipose-derived stem/stromal cells (ASCs) and naturally-derived bioscaffolds for applications in musculoskeletal tissue regeneration (adipose tissue, intervertebral disc, cartilage, ligament), therapeutic angiogenesis, and wound healing. Her lab has specific expertise in the design of biomaterials derived from the extracellular matrix (ECM) of decellularized tissues as tissue-specific, cell-instructive scaffolds. In particular, Dr. Flynn holds patents related to novel biomaterials fabricated from decellularized adipose tissue (DAT) and is working towards the commercialization of her DAT technologies for use in soft tissue reconstruction and augmentation, as well as for the treatment of chronic wounds.

Titanium alloys, electrospun scaffolds, natural polymers, connective tissues, material surface functionalization

Dr. Hamilton's philosophy on biomaterials development is to use biological data from in vitro and in vivo models to re-design materials to further promote desired cell behaviour, and advantageous gene and protein expression. Through characterization of the material chemistry and topography, as well as the cellular response, materials can be furthered adapted where applicable, through the incorporation of biologically active molecules on the surfaces. They are developing a rigorous screening system for gene and protein changes in newly implanted, as well as end stage failure biomaterials.

Dr. Sham’s research covers the general area of the chemistry and electronic properties of materials and the development and application of synchrotron radiation, especially the interplay of electronic structure, materials properties and synchrotron techniques. His areas of expertise include nanomaterial synthesis with emphasis on C and Si-based materials as well as metal oxides, surface and interface, photoemission, x-ray absorption, photon-in photon-out spectroscopy (x-ray emission, x-ray excited optical luminescence, resonant and non-resonant inelastic x-ray scattering via the x-ray and the Auger channel) and x-ray microscopy. His recent interest concerns nanostructure assembly and proximity effects, light emitting phenomena from composite nanostructures in the energy and time domain, microbeam analysis of tissues, energy transfer dynamics in nanostructures and industrial materials for drug delivery, Li battery and fuel cell applications.

Electrochemistry of materials; corrosion science and engineering; development and application of surface analytical techniques

Research in the Shoesmith laboratory is focussed on the electrochemistry and corrosion science of metal and ceramic oxide systems with a primary emphasis on industrial and environmental applications. Experimentally, the primary goal is to understand the mechanisms and determine the kinetics of a range of reactions involved in surface processes. Based on these fundamental studies, computational models are then developed to describe the behaviour of complex material systems in specific industrial/environmental environments. Presently, these methodologies are being applied in the following areas: (i) the development of nuclear waste containers and the degradation of nuclear waste forms; (ii) the evolution of corrosion conditions on gas transmission pipelines; (iii) the application of light metals in automobile manufacturing; (iv) the performance of in-reactor nuclear materials.
